Mailgun Integrations: Native, Zapier, and API
Mailgun’s integration story is developer-first. The catalog runs to roughly 50 first-party plugins across CMS, ecommerce, and backend frameworks, plus another 6,000+ apps reachable through Zapier and Make. The important distinction for buyers is between integrations that expose Mailgun as a drop-in SMTP or API driver (deep, code-owned) and integrations that bridge Mailgun events into other tools (thinner, no-code). The directory below flags each with a type badge so you can tell them apart before committing.

Frequently asked questions
Does Mailgun have a native WordPress integration?
Yes. The official Mailgun plugin lives in the WordPress plugin directory and routes wp_mail() through Mailgun via either SMTP or REST API. It tracks bounces and complaints back into Mailgun’s suppressions and works out of the box with WooCommerce, Contact Form 7, and any plugin using wp_mail().
How many total integrations does Mailgun support?
Mailgun ships approximately 50 first-party plugins and SDKs covering CMS, ecommerce, frameworks, and monitoring tools. Beyond that, Zapier adds another 6,000+ apps through Mailgun triggers and actions, and Make, n8n, and Pipedream provide additional bridges. Anything not covered natively or via workflow tools connects through the REST API v3.
Which frameworks have first-class Mailgun drivers?
Laravel (built into core), Symfony Mailer (bundled transport), Ruby on Rails (mailgun-ruby + ActionMailer), Node.js / Express / NestJS (mailgun.js SDK), and Spring Boot / Java (mailgun-java) all have first-party or actively maintained community drivers. Django and Flask use the Anymail library for backend integration. Rust, Kotlin, Swift, and Elixir have community wrappers only.
Can I connect Mailgun to a custom app or internal tool?
Yes, via the REST API v3. Mailgun provides official SDKs in Ruby, PHP, Python, Java, Go, .NET, and Node.js. The API supports full send, events, templates, mailing lists, suppressions, webhooks, and inbound routes. Rate limits are reputation-based rather than hard per-second caps; the practical constraint is the 0.05% complaint rate ceiling.
Does Mailgun have a Salesforce or HubSpot integration?
Not natively. There is no Mailgun AppExchange app for Salesforce and no HubSpot marketplace connector. Both are typically bridged via Zapier, Workato, or custom API integration. Buyers who need deep CRM sync should consider Postmark (also no native CRM connectors) or SendGrid (Salesforce Marketing Cloud integration exists via parent Twilio).
Does Mailgun support inbound email routing?
Yes, via Mailgun Routes. Configure expression-based matching on recipient, from, subject, or arbitrary header fields, then forward matched messages to your app via HTTP POST or SMTP forward. Common use cases: helpdesk email intake, parse-and-store archives, and reply-tracking for outbound campaigns.
Does Mailgun have an official MCP server for AI agents?
Yes. Mailgun shipped an official MCP server at github.com/mailgun/mailgun-mcp-server on December 19, 2025. Apache 2.0, Node.js, local execution only. Covers send_email, templates, mailing lists, delivery stats, suppressions, domain management, webhooks, routes, and analytics queries. See the API + MCP tab for full detail.
